Fast Max shutter speed: 1/4000s Sony RX1R II's 1/4000s shutter speed is fast enough to freeze any almost all sports action and is also helpful when you use a fast lens at largest aperture under bright sunlight.
25 Focus Points In sports photography , you keep continuous autofocus (AFC) mode on for tracking the subject and more focus means better tracking.
Good Low Light ISO A good high ISO performance is very important in sports photography in order to have a fast shutter speed.
Wireless Connection It may not be used by everyone but pro sports photographers use Wi-fi to transfer files simultaneously without having to wait to change the memory card.
Manual Exposure Mode Even though modern digital cameras features advanced algorithms to calculate the right exposure, they still may fail some difficult conditions. Manual exposure mode in these conditions helps a lot in order to achieve correct and consistent exposure.
Manual Focus Mode Compact cameras are not great at focusing moving objects especially at low light and your camera may not even fire bacause of not locking the focus, so manual focus mode is very useful at these times.
Electronic Built-in Viewfinder During a sports shoot, using a viewfinder allows the photographer to stabilize the camera and reduce the camera shake since it is closer to the body. Besides, it comes handy where LCD screens are very hard to read under bright sunlight.
External Flash Shoe When shooting indoor sports or outdoor sports at low light, an external flash may become very helpful.
RAW shooting capability RAW files contains much more color information compared to JPEGs, and gives you more room for post processing without significant quality loss. They provide wider dynamic range and option to recover shadow and highlight clipping to some degree.
Average Continuous Shooting: 5.0fps In the world of sports photography, faster is always better.
Environmental Sealings Most outdoor sports games are held in all-weather, so your camera has to be ready for difficult conditions such as rain and snow. Exposure to dust and water splashes are also very common in sports.
